Additional Context

Using Thunderbird the error comes on sent:
Sending of the message failed.
An error occurred while sending mail. The mail server responded:
Mailbox does not exist..
Please check the message recipient “[email protected]” and try again.
Such Thunderbird does not send the entire mail.

Logs are from trying external from a Gmail account.

I am seriously at a loss, as other accounts I just added the aliases and it worked flawless. Or set up the account as dedicated, same fine. Here, trying to do either, stalwart denies to take it?

I have reviewed the documentation and FAQ and confirm that my issue is NOT addressed there.

I have searched this support forum (open and closed topics) and confirm this is not a duplicate.

Based on what I found in the documentation, here are the most likely causes of this issue:

The 512 Mailbox not found error means Stalwart is accepting the connection (because kolibri.aero is a recognized local domain) but cannot resolve the specific recipient address to a local account in its directory.

Here are the key things to verify:

  1. For the alias case ([email protected] as an alias on [email protected]): The alias must reference a domain that is registered in Stalwart as a local domain. Go to Management > Domains and confirm kolibri.aero exists as a Domain object. The docs are clear: “Without a matching Domain object, the server treats messages addressed to that domain as external and refuses delivery.” If the domain exists but delivery still fails, double-check the alias is saved correctly by viewing the account in Management > Directory > Accounts and confirming the alias appears in the aliases list.

  2. For the standalone account case ([email protected] as its own account): An account’s primary address is built from name@domain where domainId is the assigned domain. If you created the account with name = athena.cearis and domainId pointing to the kolibri.aero domain object, the resulting emailAddress should be [email protected]. Verify in the WebUI that the account’s email address is shown exactly as [email protected] – a common mistake is creating the account under the wrong domain (e.g., kolibri.org instead of kolibri.aero), in which case Stalwart simply can’t find it.

  3. Typo check: Your report mentions both kolibri.org and kolibri.aero – please confirm which domain is actually configured in Stalwart and which one the mail is being sent to. A mismatch (e.g., account on kolibri.aero but domain object only for kolibri.org) would produce exactly this error.

Relevant docs: Domains overview and Account object reference.

It’s both kolibri.aero. [email protected] delivers, [email protected] does not. [email protected] delivers.
[email protected] does neither deliver if defined as an alias for [email protected] (local part athena, domain c-orbis.org), not as a stand-alone account athena.cearis assigned to domain @kolibri.org, naturally with restart of stalwart to make sure it’s reloaded all config changes.

On the alias (copy/paste):

Local Part*

The local part of the email alias (the part before the @ symbol)

athena.cearis

Domain*

Identifier for the domain of the email alias (the part after the @ symbol).

kolibri.aero

Description(optional)

Description of the email alias

Enabled

Defining the alias, I must select the domain from the ones served by stalwart and set up in settings “domains”. So that should simply take mail addressed to [email protected] and drop it in the mailbox for athena, not returning an error 512.
If set up as it’s own account (alias removed naturally before with a restart) it should simply deliver to the new account that I can set up in Thunderbird, but not mail to (error 512).

With the log saying “Cache hit” right before “mailbox does not exist” I’m wondering if it is a negative cache hit. I’m curious what would happen if you went to Actions and cleared the caches and then sent another message.

5

The “Cache hit” right before “Mailbox does not exist” points at a stale negative cache: if that address was looked up before the account or alias existed, Stalwart caches the negative result for up to an hour, and creating the account doesn’t currently flush that entry. That fits your pattern where earlier addresses deliver but this one doesn’t.

Try Management, then Actions, and run the invalidate negative caches action, then resend. If it delivers after that, that was the cause.

6

Didn’t help. I tried to debug myself which is especially difficult as the SQL is blobs.
I invalidated all caches and negative caches, just in case update applications, lookup stores and finally server settings.
I removed the working account, the aliases. Filter “athena” returns empty result. Restarted on system level (systemctl).
Added the account as “own account”. Run the actions, systemctl restart. Same issue. The main account delivers, [email protected] says mailbox not found.
Removed the alias. actions/systemctl, added as separate account. actions/systemctl: mailbox not found.
In the postgres table s_email I have mails with [email protected] but I think they are from import from old to new server to [email protected]. Can’t be save after all the changes I did, trying to debug to get the account to accept mails.
I removed [email protected], in case this conflicts “hidden” somewhere, restart-stunt, recreated accounts. Alias, delivers c-orbis.org but mailbox not found on kolibri.aero. Deleted, recreated as separate accounts, c-orbis.org delivers, kolibri.aero says mailbox not found.

Aside: I used [email protected] to send the mails, so the domain is set properly, works. Other accounts work.
And after delete/recreate the mail from the identical former account is gone. Still in the mailstore but no longer showing for [email protected]. Fortunately that one isn’t “live” yet, lost mails are not “relevant”. And the old ones from the old server are backed up, new ones didn’t make it to stalwart I guess.

I’m totally out of ideas, what I could still try. stalwart itself showed and shows no “errors”, it kills as soon as I try to send mail to it.
If alias a filter on accounts shows [email protected], setting up a separate accounts shows both.

7

We have done it all today again, two of us. Removed the two mail addresses. Done all “Actions”. Restarted stalwart (systemctl), then rebooted the system. Restarted stalwart again. All Actions. Then created the main mail account and secondary mail account as separate accounts. Checked, both accounts showed. Full restart stunt again. Main account works. Secondary (@kolibri.aero) says “Mailbox not found”.

Re-did it, trying main account with alias. Still for the alias “Mailbox not found”.

If I can’t get the account to run, I got order to fix it by the weekend, then returning to postfix/dovecot. Can’t be the answer, can it?

And yes, added a feature idea to improve debugging possibilities. This is a black box that even our experienced mail admin cannot help with. No help, no debugging, no good. :face_with_peeking_eye::folded_hands:t2:

If you’re not seeing something you expect in the log, have you lowered the capture level to TRACE?

As @Disrupt suggested, enable trace level and provide full logs from the delivery attempt start until the failure appears on the logs.

I do not deny possibility of PEBKAS, but that many times, someone watching over my shoulder on the retry, I would consider it unlikely in a 30+ year IT life.

You’ve exposed passwords in that log so you should change them.

It looks like you have some sort of rule that isn’t evaluating correctly since the key isn’t the full localpart name. Developer can probably point you better now that there is a log.

@Disrupt - I checked but don’t see “exposed passwords”? Checked first my own, but neither that nor another I’d recognize?

On “rules” there should not be any and none conflicting, the server is rather new. This is why I am seriously at a loss. Have started (as demanded) to prepare a fallback to postfix, which I’d much like to avoid (moving all user mails again). But if we can’t (bug-)fix stalwart, that is a severe operational risk, so I can understand the demand and have no counter argument really after the trouble we went through already. Help.

17

SMTP AUTH uses Base64 encoding. There are two of them in the logs you pasted.

I can’t help you any further. I just parsed the logs so the next knowledgeable person who comes by has something to work with.

5 days without a response, not even an idea what could go wrong here and how to resolve it? Anyone? Any idea?
